I heard something about "Schwinger variational principle" at wikipedia.. they gave the expression (in variational terms)
\delta <A|B>=<A|i \delta S |B>
Where S is the "Action" (but is an Operator..:confused: :confused: ) and the "States" |A> and |B> can vary "smoothly"..what do you get with this?...
- Could someone explain how it works and what is it used for ?...
